This seems to have been an update publication issue in a version of Ubuntu that is no longer supported (14.10), I don't think there is bug described here that still exists.
I am setting this to "Incomplete" to give some time for anyone to confirm being affected by this, I am also downgrading severity from "Critical". ** Changed in: grub2 (Ubuntu) Status: Triaged => Incomplete ** Changed in: hundredpapercuts Status: Confirmed => Incomplete ** Changed in: grub2 (Ubuntu) Importance: Critical => Medium ** No longer affects: linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1528345 Title: grub or kernel update broke Secure Boot by putting grubx64.efi instead of shimx64.efi in EFI boot order To manage notifications about this bug go to: https://bugs.launchpad.net/hundredpapercuts/+bug/1528345/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
